a CV curves of Cu NP@PC in 0.1 M KOH with the presence of glucose at different concentrations of 2, 4, 6, 8 and 10 mM. Scan rate: 100 mV/s; b The amperometric responses of Cu NP@PC upon successive addition of glucose solution in 0.1 M KOH at 0.55 V (vs Ag/AgCl); c The amperometric responses of Cu NP/C upon successive addition of glucose solution in 0.1 M KOH at 0.55 V (vs Ag/AgCl); and d The corresponding calibration curves of the Cu NP@PC and Cu NP/C for glucose sensing. The error bars were obtained based on three repeats of the experiment
